Description of the Related Art A resin mortar is one in which only a synthetic resin is used as a binder instead of a cement paste, and a filler, a fine aggregate and, if necessary, an additive are added and kneaded and cured. Resin mortar has features such as faster strength development, less cracking, and better chemical resistance than conventional cement mortar. Therefore, in the field construction, early strength, adhesiveness, wear resistance,
It is used for road surface repair using watertightness, dam apron, waterway repair work, floor work such as corrosion resistant lining. Among these application examples of resin mortar, one using an epoxy resin as a binder is known for road surface repair. However, although the epoxy resin road surface repair material has higher strength than that of asphalt concrete, it has a problem that the asphalt concrete around the repaired portion is destroyed because the elongation is relatively small. In order to improve this problem, it has been proposed to use a room temperature curable resin that is cured by radical polymerization at room temperature as a binder (Japanese Patent Laid-Open No. 7-118048).

阻害を受けにくいので、特に好ましい。As the room temperature curable resin, a mixture of a resin component such as a (meth) acrylic acid ester-based polymer, a vinyl ester resin, an unsaturated polyester resin and a (meth) acrylic acid ester-based monomer is used. The mixing ratio of this resin component and the (meth) acrylic acid ester-based monomer is preferably 10/90 to 60/40 by weight. If the mixing ratio is too small, the toughness of the cured resin mortar is poor, which is not preferable. If this mixing ratio is too large,
This is not preferable because the viscosity of the resin mortar becomes high and the mixing workability and workability deteriorate. As the (meth) acrylic acid ester-based monomer, a methacrylic acid ester-based monomer such as methyl methacrylate or dicyclopentenyloxyethyl methacrylate or an acrylic acid ester-based monomer such as dicyclopentenyloxyethyl acrylate is used. Of these, dicyclopentenyloxyethyl methacrylate is particularly preferable because it has a low viscosity, a low odor, an air-drying property, and is unlikely to be inhibited by oxygen during curing.

As an example of the polyvalent metal complex, an acetylacetone complex is well known, and examples thereof include cobalt acetylacetonate and manganese acetylacetonate. These are preferably used in the range of 0.01 to 5% by weight with respect to the room temperature curable resin and exhibit a function of promoting the action of the organic peroxide. In order to further accelerate the curing, amines such as aniline, N, N-dimethylaniline, N, N-diethylaniline, toluidine, N, N-dimethyl-p-toluidine and N, N-di (hydroxyethyl) toluidine are used. You may add as needed. Its usage is

る。The ultrafine particle filler prevents the cold-curable binder-forming material in the resin mortar from separating from the fine aggregate, and close-packs the fine aggregate to improve the strength of the cured resin mortar. Formulated for the purpose. The ultrafine particle filler enables finer packing of fine aggregate as the particle size becomes finer, so the specific surface area measured by the Blaine method is 10,000 cm.
It is preferable to use those of 2 / g or more. Such a material is silica fume. Silica fume is an amorphous silica particle that is close to a true sphere, and typically has a particle size of about 0.2 μm. The compounding amount of the ultrafine particle filler is
30 for 100 parts by weight of room temperature curable binder material
To 110 parts by weight, more preferably 35 to 90 parts by weight. If the amount is less than 30 parts by weight, the dispersion with the fine aggregate is poor and the particles are separated. If the amount exceeds 110 parts by weight, the room temperature-curable binder-forming material is not sufficiently wet, so that some portions cannot be mixed. An example of a commercially available product of a preferable silica fume is Efaco silica (specific gravity: 2.

で好ましくない。The fine aggregate is mainly composed of an aggregate having a diameter of 5 mm or less, and the rock quality is not particularly limited as long as it is rock that can be used as an aggregate for cement mortar. When a resin mortar is formed using fine aggregate, it is not necessary to select the fine aggregate considering the alkaline aggregate reaction. As the fine aggregate, either natural sand or crushed sand may be used, and for example, weathered granite mountain sand (external dry specific gravity of 2.56), silica sand (external dry specific gravity of 2.64) and the like are used. The amount of fine aggregate is 1
50 to 350 parts by weight with respect to 00 parts by weight,
The range of 60 to 280 parts by weight is more preferable. If the amount is less than 50 parts by weight, the amount of resin increases and cracks are likely to occur.
If it exceeds 50 parts by weight, the workability of the resin mortar is deteriorated, which is not preferable.

うな位置に埋設することが好ましい。The mesh woven fabric embedded in the intermediate layer of the resin mortar composition is a net-woven fabric of natural fibers or synthetic fibers having a mesh spacing of 5 to 15 mm. Cellulose fibers, vinylon, nylon, polyester, carbon fibers and the like can be used as the material, but carbon fibers and vinylon are particularly preferable in terms of adhesion to resin mortar and strength. The thickness of the mesh woven fabric and the number of mesh fabrics to be used can be appropriately changed depending on the construction thickness of the resin mortar and the required degree of crack resistance, but it is most important that the mesh spacing is 5 to 15 mm. When the mesh spacing is less than 5 mm, the resin mortar is not completely attached to the upper and lower parts and the resin mortar and the mesh woven fabric are not integrated with each other, so that the resistance to cracking under cold weather is lowered, which is not preferable. When the mesh spacing exceeds 15 mm, the reinforcing effect of the mesh woven fabric is reduced, and the crack resistance in cold weather is also reduced, which is not preferable. The embedding position of the mesh woven fabric is preferably such that the embedding position is 1/2 to 2/3 from the bottom with respect to the entire depth of filling the resin mortar composition.

(1) Dry the construction site such as the road surface. When the road surface temperature is low, the curing of the resin is delayed, so it is preferable to heat the road surface with a gas burner or the like. A torch lamp, a gas burner or the like can be used as the drying means. (2) Remove dust on the road surface. As a means, a vacuum, a broom, etc. can be used. (3) In order to improve the adhesion between the construction site and the resin mortar, it is preferable to apply an undercoating agent in advance. As the undercoating agent, a material for forming a room temperature curable binder is preferable.
